CVE-2019-4186

Estado: ModificadaMedia (6.1)—

IBM Jazz for Service Management 1.1.3 is vulnerable to HTTP header injection, caused by incorrect trust in the HTTP Host header during caching. By sending a specially crafted HTTP GET request, a remote attacker could exploit this vulnerability to inject arbitrary HTTP headers, which will allow the attacker to conduct various attacks against the vulnerable system, including cross-site scripting, cache poisoning or session hijacking. IBM X-force ID: 158976.
